obama. and right now this study is very good news for democrats. >> trace gallagher thanks. >> they are tracking everything we do. they are in the skies. they are everywhere. and now a digital advertising company is agreeing to end a practice called history sniffing. after the feds told him to knock it off. the company is called epic market place. and what it reportedly did was install tracking software secretly on your computer. that software then gathered data about the websites you visited. and it sent that data back to the company. epic market place used it to target advertisements without consent of any kind. if you went on-line to look at websites on bankruptcy for instance, the company in theory knew that's what you were doing and knew about your possible money problems and not necessarily illegal, but it does raise privacy concerns that they will not tolerate. so they found one way that they watch everything we do. sud -- suddenly they don't want it to hoop. don't want it to happen.
